AVIS
Risque de défaillance de compresseur !
N'utiliser le compresseur que dans le sens de
rotation prescrit !
Les séries de compresseurs CS.65, CS.75, CS.85,
CSH76 et CSH86 sont équipées de série de moteurs à
bobinage partiel (Part Winding, « PW ») avec
connexion Δ/ΔΔ. En option, elles peuvent également
être équipées de moteurs à étoile/triangle (Y/Δ). Pour
des informations détaillées, se reporter au manuel
SH-170.
Les modèles CS.95, CSH96 et CSW105 sont générale-
ment équipés de moteurs à étoile/triangle (Y/Δ).
Moteurs à bobinage partiel (PW)
Méthodes de démarrage :
• Démarrage à bobinage partiel pour réduire le cou-
rant de démarrage.
• Démarrage direct.
Retard de temps avant l’allumage du 2ème bobinage
partiel : 0,5 s max. !
Effectuer correctement les raccordements ! Une erreur
d’arrangement des raccords électriques aboutit à des
champs tournants contraires ou à l’angle de phase dé-
calé, et donc à un blocage du moteur !
Raccorder les bornes du moteur au couvercle de la
boîte de raccordement conformément aux instructions.
Tenir compte absolument de l’ordre des bobinages par-
tiels !
• 1er bobinage partiel (contacteur K1) : Raccords 1 /
2 / 3.
• 2ème bobinage partiel (contacteur K2) : Raccords 7 /
8 / 9.
• Partage de bobinage 50%/50%.
• Répartition des contacteurs moteur :
– 1er contacteur (PW 1) : 60% du courant de ser-
vice max.
– 2ème contacteur (PW 2) : 60% du courant de ser-
vice max.
Moteur à étoile-triangle
Le retard de temps entre la mise en route du compres-
seur d’un côté et, de l’autre, la commutation entre
l’opération en étoile et celle en triangle ne doit pas dé-
passer les 2 s.
Effectuer correctement les raccordements !
Toute erreur d’arrangement des raccords électriques
aboutit à un court-circuit !
Information
Les contacteurs réseau et triangles doivent être
calculés à au moins 60% du courant de service
max., le contacteur étoile à 33%.
5.3 Essai de haute tension (test de résistance
d'isolation)
Les compresseurs ont déjà été soumis avant leur sortie
d’usine à un essai de haute tension conformément à la
norme EN12693 ou conformément aux normes UL984
ou UL60335-2-34 pour la version UL.
!
!
AVIS
Risque d'endommagement de l'isolant et de dé-
faillance du moteur !
Il ne faut surtout pas répéter l'essai de haute
tension de la même manière !
Un nouvel essai de haute tension ne doit être réalisé
qu’à une tension alternative max. de 1000 V CA.

ВНИМАНИЕ
Опасность выхода из строя компрессора!
Эксплуатация компрессора только с
предусмотренным направлением вращения!
Компрессоры серий CS.65, CS.75, CS.85, CSH76
и CSH86 стандартно оснащаются моторами с
разделенными обмотками (Part Winding «PW») с
подключением по схеме Δ/ΔΔ. По специальному заказу
могут поставляться также моторы «звезда-треугольник»
(Y/ Δ). Подробную информацию смотрите в руководстве
SH-170.
Модели CS.95, CSH96 и CSW105 - всегда оснащаются
моторами «звезда-треугольник» (Y/ Δ).
Моторы с разделенными обмотками (PW):
Методы пуска:
• Пуск мотора с разделенными обмотками для
снижения пускового тока
• Прямой пуск
Временная задержка подключения второй разделенной
обмотки составляет: максимум 0.5 сек.!
Правильно подключайте соединения! Неправильное
подключение разделенных обмоток ведёт к изменению
направления или ослаблению вращающихся полей
за счет изменения межфазовых углов. Это приводит к
блокировке мотора!
Осуществляйте подключение клемм в соответствии с
эл. схемой на крышке клеммной коробки.

NOTICE
Risk of compressor failure!
Operate the compressor only in the intended ro-
tation direction!
The compressor series CS.65, CS.75, CS.85, CSH76
and CSH86 and are equipped by default with part-wind-
ing motors ("PW") in Δ/ΔΔ-wiring. Star-delta motors (Y/
Δ) are also available as an option. For detailed informa-
tion, see manual SH-170.
The CS.95, CSH96 and CSW105 models are generally
equipped with star-delta motors (Y/Δ).
Part-winding motors (PW)
Starting modes:
• Part-winding start to reduce the starting current.
• Direct start.
Time delay until switch-on of the 2nd part winding: max.
0.5 s!
Make the connections correctly! Wrong electrical con-
nections will lead to opposite fields of rotation or to
fields of rotation out of phase and therefore to a motor
lock!
Connect motor terminals on the cover of the terminal
box according to the instructions.
Strictly observe the order of the part windings!
• 1st part winding (contactor K1): connections 1 / 2 / 3.
• 2nd part winding (contactor K2): connections 7 / 8 /
9.
• Winding partition 50%/50%.
• Motor contactor selection:

current.
– 2nd contactor (PW 2): 60% of the max. operating
current.
Star-delta motor
The time delay between switch-on of the compressor
and switch-over from star to delta operation shall not
exceed 2 s.
Make the connections correctly!
Wrong electrical connections will lead to short-circuit!
Information
Rate the mains contactor and the delta con-
tactor at min. 60% and the star contactor at min.
33% of the max. operating current.
5.3 High potential test (insulation strength test)
The compressors were already submitted to a high po-
tential test in the factory according to EN12693 or ac-
cording to UL984 or UL60335-2-34 for the UL model.
!
!
NOTICE
Risk of defect on the insulation and motor fail-
ure!
Never repeat the high potential test in the same
way!
A repeated high potential test may only be carried out
with max. 1000 V AC.
5.4 Protection devices
WARNING
Risk of electric shock!
Before performing any work in the terminal box
of the compressor: Switch off the main switch
and secure it against being switched on again!
Close the terminal box of the compressor before
switching on again!
!
!
NOTICE
Potential failure of the protection device and the
motor due to improper connection and/or faulty
operation!
Connect properly according to the schematic
wiring diagrams and check the connections for
tight seat.
The cables and terminals of the PTC control cir-
cuit must not come into contact with the control
voltage or operating voltage!
5.4.1 SE-E1
This protection device is incorporated as standard in
the terminal box of all HS.53 .. HS.85 compressors and
CSH, CSW compressors. In the state of delivery, the
cables for the monitoring of motor and oil temperature,
rotation direction and phase failure are connected to
the terminal plate. Other connections according to the
wiring diagram in the terminal box, see manual SH-170
and Technical Information ST-120.
Monitoring functions:
• Temperature monitoring.
• Rotation direction monitoring.
• Phase failure monitoring.

5.1 Основные подключения
При определении параметров контакторов, кабелей и
предохранителей:
• Необходимо исходить из величины максимального
рабочего тока или максимальной потребляемой
мощности мотора.
• Выбирать контакторы категории применения AC3.
• Определять параметры тепловых реле перегрузки по
току на основе величины максимального рабочего тока.
Строго соблюдайте порядок подключения
разделенных обмоток!
• Первая разделенная обмотка (контактор К1):
соединения 1 / 2 / 3
• Вторая разделенная обмотка (контактор К2):
соединения 7 / 8 / 9
• Распределение тока по разделенным обмотками
50%/50%.
• Определение параметров контакторов
производится исходя из:
– 1-й контактор (PW 1): 60% от максимального
рабочего тока.
– 2-й контактор (PW 2): 60% от максимального
рабочего тока.
Мотор «звезда-треугольник»
Временная задержка от включения компрессора
до переключения со «звезды» на «треугольник» не
должна превышать 2 сек.
Правильно подключайте соединения!
Неправильное подключение обмоток может привести к
короткому замыканию!
Информация
Главный контактор и контактор для включения
обмотки «треугольником» подбирайте из
расчета не менее 60% от максимального
рабочего тока, контактор для включения
обмотки «звездой» на 33% от максимального
рабочего тока.

(испытание электрической прочности
изоляции)
Компрессор уже был испытан высоким напряжением
на заводе, в соответствии с EN 12693 или при UL-
исполнении согласно UL984 или UL60335-2-34.
ВНИМАНИЕ
Опасность повреждения изоляции и выхода из
строя мотора!
Не повторяйте испытание высоким
напряжением таким же образом!
